APBARATU'S FOR EXHIBITING PICTURES, ADVERTISEMENTS, AND LIKE.

Application filed March l0, 1924.

To all echo-m it may concern:

Be it iIlOWD that I, .Gnonon Banner HART.- Lny, subject of the nling of Great Brita-in and Ireland, residing at 16 Grosvenor Road, lVattord, Hertfordshire, England, have in.- vented certain new and useful Improvements Relating .to Apparatus for Exhibiting Pictures, Advertisements, and the like, of which the following is a specification.

This invention relates to apparatus for exhibiting pictures, advertisements and the like, of the kind comprisingaseries otseparate elements disposed in the same plane and exhibiting parts of the pictures, advertisements or the like in such manner as apparently to present an unbroken picture surface and in which the elements are adapted to receive in succession an intermittent angular movement for the exposure of ,the parts of a fresh picture, advertisement or the like.

In such apparatus the said movement of the elements is advantageously effected by means oi? a travelling endless chain or the like having projections which are adapted to engage and turn the elements in succession, while it is further of advantage to provide the parts of the pictures, advertisements or the like upon endlessbands.each of which passes around one of the series of elements'before referred :to and also around an element of a second series of elements. By such a construction the advertising capacity ofthe apparatus-may"be greatly increased.

The invention has among its objects to provide an improved apparatus of the kind described in which simple and effective means are adapted to conceal the intermittent movement of the elements necessary for the successive exposure of the pictures, advertisements or the like, and generallyto provide simple and effective constructions of advertising apparatus.

According to the invention I provide a moving lath, screen or the like disposed parallel with the respective rotatable elements and adapted to movein l rontithereot and to be so set that as-the latch, screen or the like comes to lie in trontof each rotating,

element that element is moved, so that thus in the operationoi' the apparatustheillusion is presented of the new picture, advertisement or the like being exposed by the lath, screen or the like. The lath may be divided into parts which are connected together after Serial No. 698,263.

the manner of a blind, to serve as .a flexible screen.

Apparatus constructed in accordance with the invention are hereinafter described with. reference to the accompanying diagrammatic drawings by way of example.

Fig. 1 is a side elevation of an apparatus according to the invention provided with rotatable elements carrying endless bands the front of the apparatus being shown at the righthand side of the drawing.

Fig. 2 is a detail view of an endless band and .F 3 is a detail view in perspective illustrating the arrangement of the principal elements necessary for the operation v0t the apparatus.

In carrying the invention into effect in the manner illustrated in thedrawings, the parts or sectionsof the pictures, advertisements or the like are mounted upon slats i of wood, metal or other suitable material, carried by and between two endless :bands or chains j which are carried upon pairs of rotatable elements Me of square section. The pairs of elements '70 at the front of: the apparatus are mounted fixedly upon corresponding spindles Z carried in bearings m formed in the frame members m. The elements 70 at the .rear of the apparatus may be carried upon stub spindles Z mounted upon the rear frame members m. The stub spindles'l may, however, be mounted in such manner as to permitot their adjustment to wards and away TlTOlllthB front of the apparatus, for example, the stub spindles Z? may be-mounted .inslotsm inthe rear frame members and may be locked illl the adjusted position by means of lock nutsl The endless bands 7' are advantageously provided of sheet metal links 9' oi length corresponding to the length 01 the sides of the section of the elements 7070 and each being provided with a centrally disposedhole torthe engagement of pins or projections 70 provided upon the elements. The slats 2' are advantageously provided of a width whichais a multiple of the length of the side of the section of the elements 7073 and the several pairs of elements Me are disposed upon the frame members m in such positions I that the slats carried by the corresponding bands form a continuous surface when at the front of the apparatus. In the con struction illustrated the slats are provided of a width approximately three times the length 01 the side of the section of the elelit) ments 7% and are supported at the middle of their width by means of plates 2' or extensions which are introduced between the finger or clipsj of the endless bands, the said plates 2' being slotted as at 2' (Fig. 3); to permit the engagement of the pins 70*. Two endless bands or chains 72 are provided to be carried upon corresponding chain Wheels 0 mounted on spindles suitably carried in bearings provided in the frame members m or in bearing members 0 in such manner that they may be adjusted in position as by the n'iovement of the spindle along a longitudinal slot provided in the said hearing member 0 At the front of the apparatus the chains 01 are carried in proximity to the rotataliile elements 7. and in such manner that transverse laths or screen elements g) of sheet metal may extend across the face of the slats i when in the exposure positions. Four of such screen elements are indicated as carried by adjacent links of the chains 71 and in their passage across the face of the slats i in the exposure position serve to mask the movement of rotation of the elements I? effected by the Geneva stop devices. The screen elements 2 are supported from the links of the chains a by sheet metal angle brackets 71 formed integrally with the inner links a of the chains.

The Geneva stop devices 9 for each pair of elements 70 is carried upon a boss 723 formed on the outer side of one of the elements 7c at the front of the apparatus and rotation of the said devices is effected by pins 02. provided in extension of the connecting pins a of those links of the chains a by which the screen members- 1) are supported.

In order that the Geneva stops may be maintained stationary during the time that the slats are exposed the links of the chain 91 adjacent the said stop devices other than those between the operating pins n. are formed with lateral extensions 11" adapted to serve as a bearing surface against which the Geneva stops may engage, such bearing surface being supported by means of a bar r or the like provided for the purpose, the said bar being recessed as at F innnediately opposite the Geneva stop devices to permit of their rotation. Those links next adjacent the operating pins 92. may, if necessary, be provided with lateral extensions for half the length of the link only (as shown in Fig. in order to provide clearance for the rotation of the Geneva stops.

In the case of apparatus disposed in elevated positions and constructed in the manner hereinbefore described, the rotatable elements upon the faces of which the respective sections of the pictures, advertisements or the like are applied or upon which end less bands are mounted in the manner de scribed, are advantageously so set in position for exposure that the respective elements are substantially horizontal and have their upper edges protruding slightly in front of their lower edges so that inas much as the line of vision is directed upwardly, the top edge of each rotatable element obscures the lower edge of the next higher element. In the construction illustrated this effect is secured by the inclination of the slats z' with reference to the end less bands 7' supporting them. This result is conveniently secured by the inclination of the seatings on the slats upon which the plates 5 are applied. It may, however, be secured in any other convenient manner.

It will be understood that the invention comprises the constructional features which are hereinbefore described but it is not limited thereto. Thus in the construction described with respect to the drawings the width of the slats with respect to the length of side of the section of the elements may be greater in proportion than that indicated in the construction described.
